MUSIC-LEAF TURNER.

To all whom it may concern:

Be it known that I, EDWARD HANDLER, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful In'iprovements in Music-Leaf Turners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being-hadto the accompanying drawings, and to figures of reference markedthereon, which form a part of this specification.

This invention relates to a music leaf turner which is adapted to bedetachable on a suitable music support, such as a piano or a musicstand, and is designed to collapse so that it can be easily carriedabout, and one that can be easily set up and secured in place and haveits parts opera tively connected.

The invention is designed for turning sheets of music and is illustratedand is particularly adapted for use with music having a single insertleaf, which is the usual type of music now employed, the .devicebeingadapted to operate by a pressure of the finger on a suitabletripping device.

The invention further consists in a device of this kind which is simpleto operate and which can be easily kept in order and is not apt to failin its operation because it is ex tremely simple in its construction.

The invention is illustrated in the accompanying drawing, in which-Figure 1 is a View of the music leaf turner set up and showing a pieceor sheet of music in dotted outline. Fig. 2 is a top view of the musicleaf turner showing the device when it is collapsed. Fig. 3 is a frontview partly broken away, and Fig. 4 is a side view of thespring-actuated turning means and a cap covering the same. Fig. 5 is adetail view showing a clamp used in attaching the turner to one type ofsupport, such as the front panel of a piano, and Fig. 6 is a similarviewof a modified form of clamp for attaching the device to a different typeof front panel.

A number of different embodiments can be used with this invention, andchanges can be made in the disposition and proportion of the parts andin the details of the construction, but the preferred form of de-Specification of Letters Patent.

vice is illustrated in the drawing above described.

The music leaf turner consists of a frame having side bars 10 and 11 anda top bar 12. The side bars are hinged at 13 to the top bar, one bar atits pivotal end 13 having a washer or a suitable device 1 1, the otherside bar having a washer or collar 15 or a similar device for permittingthe side bars 1.0 and 11 to swing in different planes so that they canfit alongside of each other when swung to the position shown in Fig. 2.In this figure the side bars are illustrated as both swinging to therear of the top bar, although this particular disposition is notessential. To the top bar is secured a suitable pin 16 which acts as apivot for the arm 17 the arm swinging on or with the pin and having onits end a suitable clip 18, the clip having the fingerpieces 19 wherebyit can be manipulated. to open the jaws, the jaws being normally heldtogether by a spring 20. The arm 17 is slightly resilient, having enoughspring to it to permit it to be sprung over a hook 21 on the oppositeside of the top bar 12 from the normal position of the clip, the clipbeing held in its normal position by a spring 22 which is arranged tobear on the arm 17 so that the arm is swung to the left whenever it isreleased. In practice the insert sheet of a piece of music 2% is securednear its outer end by the clip 18 and the arm 17 is then swung againstthe pressure of the spring 22 so that the arm is seated in the hook 21,the hook being open at the top.

On the top bar is a suitable eye 2st through which passes a rod 25, therod preferably having a flange 26 on its top edge, the top end of therod 25 being arranged in the eye 24 and being so disposed that it isunder the arm 17 when it is in the dotted position shown in Fig. 1, thatis, to the right, from which position the music is to be turned. The eye24 is preferably made so that it can rotate in the bar 12. The lower end27 of the rod 25 is screw-threaded and is screwed into a. collar 28 onthe lever 29, the lever when the music is clamped in the clip 18 and isin the position shown in dotted outline in Fig. 1, and when the music isto be turned, a slight tap or blow on the finger-piece or handle 31 willcause the lever 29 to be tilted on its pivot 30, the rod 25 is forcedupward, and in turn the upper end of the rod 25 pushes the arm 17 upsufliciently to have it clear the top edge of the hook 21, and thespring 22 is then free to swing the arm 17 to the position shown in fulllines to the left of Fig. l and the music is turned.

In the case of a front panel that is provided with a shelf at thebottom, as shown at 33 in Fig. 5, I place the side bars against thefront panel and suitable clamps, each consisting of a metal strip 3%,are placed so that the end 35 and the intermediate portion are on thebottom and top surfaces of the shelf 33, and a suitable set-screw 3Tclamps the parts together. The upwardly projecting end 38 is providedwith a setscrew 39 which bears against one side bar of the frame andholds it in place.

In Fig. 6 is illustrated a modified form of clamp which is employed whenthe shelf 40 is separate from the front panel s'l of the piano. In thiscase I use a J-shaped clamp one of the arms of which, as 43, is providedwith a set screw ts, the end of which, with. a suitable washer is usedto clamp the side bars to the frame of the piano or music stand. Thisleaf turner can be easily collapsed and easily set up, either operationtaking but little time.

lVhen the device is to be assembled from the position shown in F 1, therod 25 is unscrewed from the collar 28 and then swung in close to thetop bar as shown in Fig. 2, the lever 29 can then be swung in alinementwith the side bar 11, as is best illustrated in Fig. 2, and after havingbeen unclamped from their support, the side bars 10 and 11 are swung ontheir pivot 13 and are alined with the top bar 12. it will thus be seenthat when collapsed the turner provides a long, narrow ackage and iseasily placed in the average music case or is easily carried in thehand.

The material of which the device is made is immaterial to its successfuloperation, since any suitable material can be us-d, but I prefer to makethe side bars and the top bar of thin wood, and the arm 17 of springmetal and of a size calculated to make its bending somewhat easy so thatits insertion into and its springing from the hook 21 is easilyaccomplished.

I prefer to cover the pin 16 with a shell. 1-6 which is slotted at 47,the slot -17 acting as a guiding means for the arm 17, the shell &6protecting the spring 22 and acting, preferably, as a support or hearingfor the pin 16. The shell 4-6 is usually secured by means of lips f?which are integral with the shell and are clamped over the top andbottom edges of the top bar.

Having thus described my invention, what I claim is 1. A music leafturner consisting of a frame, the frame having a top bar and two sidebars pivoted thereto in a manner to pcrmit their being swungsubstantially parallel with the top bar, a spring-actuated music leafturning device on the top bar, means for restraining the action of theturning device, and manually operated means for forcing the turningdevice from the restraining means.
